このボードに関する情報はここにまとまってあります(ピンレイアウトを除く）。 (2016/12/03追記) こちらの記事も参考になると思います。 「Red Pill or Blue Pill?」 「Red Pill or Blue Pill?」によると、私のはBlue Pillボードで、USB接続に問題ありとの 情報があります（USB用のPA12ピン接続のR10の抵抗に問題あり？） 。
インストールしたファイルをチェックすると .\hardware\Arduino_STM32\examples にサンプルソースがありました。その中の\Digital\Blink\Blink.inoを見ると digitalWrite(PB1, HIGH); // turn the LED on (HIGH is the voltage level) となってました。
I2C. Working, However this is a software (bit-banged) implementation, and has a maximum speed of around 250kbps. Speed improvements. Hardware I2C has been tested by some users, but is not integrated into the normal Wire library.
次の文面を発見 To communicate with the Nunchuk,we must send a handshake signal. If you are using a black Wii Nunchuk, send 2 bytes 0xF0, 0x55 to initialize the first register and 0xFB, 0x00 to initialize the second register of the Nunchuk. On a white Wii Nunchuk, send 0x40, 0x00 followed by 0x00.
